ANTISKIDDING-ARMOR FOR TIRES.

To all whom it may concern:

lie it known that I. WILLIAM M. PAUL, a citizen of the United States. residing at New York. in the countv of New York and State of New York, have invented certain new: and useful Improvements in Antiskidding-Armor for Tires; and I do declare the following to he a full, clear. and exact de- -script.ion' of the invention. such as will enable others skilled in the art to which it apa-rtains to make and use the same. This invention relates to anti'skidding armor for pneumatic tires and it consists in the construction and arrangement of parts, as will be hereinafter described and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 -is a side elevation of a wheel showing the application of my improved armor; Fig. 2 is a sectional: view taken on the line 22 of Fig. 1; l ig. 3 isa similar view on the line 33-41] of Fig: 1; Fig. 4 is a plan view of one section of-the armor; and l igs. 5 and (S are detail sections on the lines 5-5 and 6-6 of Fig; 4, respectively.

Similar reference characters indicate corresponding views.

ltc/r'crrin p:n'ticularly to the drawingsfl designates a vehicle wheel of any desired type or size having a rim 9 in which is separts throughout the several cured a pneumatic tire 3. In the practical eml'md1ment of my invention, I employ a cured upon the ends of the tread sections by rivets or bolts.

To secure the tread sections 4 is position upon the tread of the tire, and at the same time permit them to freely move to. accommodate themselves to all of the movements or deprcssit-ms of. the tire during the travelol' the vehicle. I employ a pair of retaining; rings 7, in which are provided a pluralit v of spaced apertures 8 tor-the reception of one end ol'll e coilspringslt'i, which are snit- Specification of Letters Patent.

ably secured at their opposite ends to the hooks 5 carried by the tread sections 4. One of these coil sarings is preferably secured at each end 0 each of the tread sections, and they serve to at' all times hold the sections against the periphery of the tire'while allowing the leather sections to be depressed with the pneumatic tire when the wheel passes .over a stone or other 'obstacle' in the road. It will also be apparent that if any of the tread sections 4 becomes cut, or worn by reason of its contact with glass or other sharp objects encountered in the road, the tread sections may be instantly removed by uncoupling the ends of the springs 9 from the hooks 5 upon that articular tread section. Thus theinjure tread sections. may be immediately removed and replaced by Others without disturbing the remainiiig tread sections upon the tire. r

The retaining rings 7 are preferably divided, and, as herein shown, comprise two substantially similar sections which are hingedly connected, as at 11, to each other, while a suitable clamp or locking means is carried hythe opposite ends of these sections. to secure or lock the ring sections inposition upon the vehicle wheel. Owing to this'construction the entire armor may be removed from about the vehicle tire without detaching the separable tread sections, by unlocking or unelamping the retaining rings (3 and swinging the sections upon their hinges until the tread sections and retaining rings may he slipped from the vehicle tire.

In order to prevent excessive wear upon the tread sections 4 and to provide an antiskidding device. whereby the vehicle may obt-ainv a firm hold upon the ground at all I time's, I preferably secure upon the outer face of each of the tread sections 4, a plurality of spurs or studs 12, which are provided with portions adapted to project radially with relation to the. vehicle wheel when the tread sections are in position upon the tiref These spurs or studs 12 are pref crably arranged in the following manner: At- .substantially the central portion of each of the tread sections 4 are provided metallic.

studs 13 of any desired shape and suitably secured to the leather or like material of the tread section. At each side of the central studs and arranged so that the lower flange of each of the studs engage the sides of the tread sections, are T-shaped spans 14., the

body portion or shank of-which is secured to the tread section by means of bolts or rivets 16, while the uppermost flange projects at substantially right angles from the face of the tread section. Spaced fromthe T-shaped spurs and arranged on each side thereof, are provided I-shaped spurs or studs 17, the body portion or shank 18 of which is riveted or otherwise secured to the tread section, as clearly indicated in Fig. 3, while the lowermost flange of each spur en' ages the side edges of the tread section, an the uppermost flange projects at substantially -of the kind described that the right angles from the outer face of the tread section. The lower flanges of the T-shaped spurs 14 and the I-shaped spurs 17 extend to a point slightly above the lower face of the tread sections 4 and do not contact within'the-periphery or tread of the vehicle tire.

It will be seen that when the armor sections are provided with the grippin devices heads of the devices on ad'oining sections will. bear one against the ot er and so.preventethe sections from shifting their position and riding up one over the other.

' From the foregoing it will be apparent that-I have deyiced a reinforcing and anti skidding armorfor fvehicle tires composed -shaped of a plurality of separably independentsections, each of which carries a plurality of anti-skidding means and which may be 1 singly or collectively secured about the tire of the vehicle wheel when desired.

From the foregoing description taken in connection with the accompanying drawings,'the construction and operation of the invention will be readily understood without requiring a more extended explanation. Having described my invention, I claim: In a tire armor, the combination with a flexible strip adapted to be secured trans-- versely across the tire, of a grippin device my hand in presence of two subscribing witnesses.
